Answer:
See figure 1
Explanation:
In this question, we have to remember that each <u>carbon has 4 electrons</u> and each <u>hydrogen has 1 electron</u>. Additionally, the structure proposed have to have <u>8 electrons for each atom</u> <u>(except hydrogen)</u>. With this in mind, we need to have a <u>double bond</u> between the carbons, because in this arrangement each carbon would have 8 electrons <u>(octet rule)</u>.
See figure 1

After 17190 years, Carbon-14 will reach a mass of 15 grams.
Pi is your initial amount (120 grams)
0.5 as your exponential base represents your HALF life hence 0.5
t represents the time elapsed
c represents your given half life value of (5730)
P(t) represents the exponential function of your half life
120/2 =60
60/2 = 30
30 /2 = 15
As you can see above, 3 half lives of 5730 years EACH degraded the carbon-14 to 15 grams. You divide each number by two as it is a HALF life.
P(t)= Pi (0.5) ^t/c
P(17190) = 120 (0.5) ^17190/5730
P(17190) = 120 (0.5) ^3
P(17190) = 15 grams
So your answers should be 3 half lives or after 17190 years have elapsed!
Single-nucleotide polymorphisms (SNPs) are highly abundant markers, which are broadly distributed in animal genomes.
<h3>What is Single-nucleotide polymorphisms ?</h3>
A single nucleotide alteration at a specific location in the genome is known as a single-nucleotide polymorphism in genetics. While some definitions call for the substitution must be present in a sizable enough portion of the population, many publications do not use this standard of frequency.
For instance, the G nucleotide may be present at a particular base position in the human genome in the majority of people, whereas an A may be present in a small percentage of people. This indicates an SNP, and the two potential nucleotide changes - G or A - are referred to as the alleles for this particular site.
SNPs identify variations in how susceptible we are to a variety of illnesses, such as age-related macular degeneration.

Answer:
The answer is
<h2>8.33 %</h2>
Explanation:
The percentage error of a certain measurement can be found by using the formula
From the question
actual volume = 60 mL
error = 65 - 60 = 5 mL
The percentage error is
We have the final answer as
<h3>8.33 %</h3>
